⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow brakes to cool before working on them to avoid burns.

Symptoms

•Shaking or vibration felt in the steering wheel or pedal when braking
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Pulsation in brake pedal
•Noise (squeaking or grinding) while braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear patterns.
3
Examine suspension components (e.g., control arms, tie rods) for wear or damage.
4
Inspect wheel alignment and balance.
5
Test brake calipers for proper operation and fluid leakage.
6
Scan for any brake system-related error codes using an OBD-II scanner.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly

Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it on jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for warping by measuring with a dial indicator.
- If warped beyond spec, proceed to replace.
Remove Old Rotors:
- Unbolt caliper bracket and slide off the caliper.
- Remove the rotor by unbolting it from the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective coating.
- Install new rotors and secure them with the appropriate torque (typically 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check the thickness; if below spec (usually less than 3mm), they should be replaced.
Remove Old Pads:
- Remove the caliper bolts and slide the caliper off.
- Remove the old pads from the caliper bracket.
Install New Pads:
- Apply brake grease to the backing of new pads.
- Insert new pads into the caliper bracket and reposition the caliper.
- Torque caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).

5. Reassemble and Lower Vehicle

Reinstall wheels and hand-tighten lug nuts.
Lower the vehicle off jack stands and torque lug nuts to specifications (typically 100-130 ft-lbs).

6. Test the Brakes

Pump the brake pedal a few times to seat the pads.
Test drive the vehicle to ensure proper brake function and check for vibrations.
